The 37-year-old actress, who is currently in Sydney to promote the highly-anticipated third instalment to the Pitch Perfect franchise with costars Brittany Snow, Anna Camp, and Ruby Rose, also refused sit-down interviews with the outlet's publications and uninvited staff to the premiere, Sydney Morning Heraldreports.

Requests by the publisher for a reason as to why a blanket ban was enforced went unanswered.

According to SMH, it is believed Wilson is disgruntled that "a request she made to Fairfax Media chief executive Greg Hywood in 2015 was revealed during her defamation trial against Bauer Media in May".

The Bridesmaids star contacted Hywood after SMH published an article that revealed her age alongside an "unflattering" photo of her. She requested the outlet take the article down, but they did not comply.

"It is against [Fairfax Media] as a brand in terms of what has gone on at the court case... and there is a number of things that have happened which representatives from Fairfax in terms of testifying against Rebel," the source said. "It's nothing personal against... any journalist."

Wilson was awarded $4.5 million in damages in her landmark defamation trial against Bauer Media at Melbourne's Supreme Court in June. During the trial, Fairfax Media responded to a court order to produce the actress' correspondence with Hywood.

"Fairfax responded to a subpoena as part of legal proceedings she commenced," a Fairfax Media spokesperson said. "We were compelled by the court to do so."

"It was just horrific, I wouldn't wish it on anybody," she said. "And then to suddenly have my fortunes turned drastically around and now] I've just done two other feature films following the court case."
